Abstract

• Nowadays, several biomaterials, including natural polymers, are used to solve and reduce the global problem of water pollution and biomedical as cellular interactions. Chitosan (CS) is one of the most studied biocompatible natural polymers. Graphene oxide (GO) is carbon-based nanomaterial capable of imparting desired properties to the scaffolds. In the present study an ecofriendly approach led to the development of biodegradable chitosan based graphene oxide bionanocomposites which have been prepared by the mixing aqueous solution of chitosan and graphene oxide. The synthesized GO and CSGO were characterized by using fourier transform infrared spectroscopy (FT IR), thermogravimetric/differential thermal analysis (TG-DTA), X-ray diffraction (XRD), field emission scanning electron microscope (FE-SEM), UV-Vis spectroscopy. Finally, the synthesized nanoparticles size and surface charge were measured by dynamic light scattering (DLS) and zeta potential analyzer, respectively. The results obtained from those different studies revealed that chitosan and graphene oxide could mix with each other homogeneously. Hence, chitosan based graphene oxide bionanocomposite were successfully synthesized and characterized.
